HSHT Fiberglass is an engineering-grade 3D material designed for durable composite manufacturing where parts must maintain strength under elevated temperatures and continuous load. As one of Markforged’s industrial reinforcement materials, it supports high strength high temp requirements for tooling, fixtures, and functional components exposed to heat, force, or sustained mechanical cycling.
HSHT Fiberglass delivers strong mechanical performance and maintains rigidity under high stress. As an industrial reinforcement material, it provides higher tensile strength and improved fatigue resistance compared to standard fiberglass reinforcement. In addition, with Markforged’s continuous fiber reinforcement process, it produces engineering-grade fiberglass components that remain dimensionally stable during repeated force or long operating cycles. This reliability supports durable composite manufacturing for teams that need consistent structural performance.
This high strength high temp 3D material retains stiffness in elevated-temperature environments, which makes it suitable for heat-forming tools, high-load fixtures, and production equipment near heated processes. In addition, its thermal stability reduces deformation and helps reinforced parts preserve alignment and accuracy during extended operation. As a result, HSHT Fiberglass supports predictable performance in workflows that demand both strength and heat resistance.
HSHT Fiberglass serves as a dependable reinforcement option for applications that require impact resistance, minimal creep, and long service life. It integrates cleanly into composite base materials and provides durable reinforcement for press tooling, end-effectors, and assembly fixtures. Since it offers consistent behavior under thermal and mechanical cycling, it also helps production teams maintain uptime while reducing part fatigue and replacement intervals.
